Recovery of zinc and copper from copper smelter flue dust

Copper smelter flue dust is a residue, rich in zinc, originating from the pyrometallurgical process of copper, and constitutes a potential raw material for zinc production. In order to valorise this waste by hydrometallurgical processes, its leaching with sulphuric acid at constant pH is studied.

Recovery of Copper from a Waste Heat Boiler Dust Leach

The dust collected from the waste heat boiler of a copper plant was leached with sulfuric acid and the leach liquor contained 31.63 kg/m 3 Cu, 14.78 kg/m 3 Fe, 2.21 kg/m 3 Zn, 0.26 kg/m 3 Co, 0.09 kg/m 3 Ni, and 0.23 kg/m 3 Cd. The iron content in the leach liquor was precipitated out using Ca(OH) 2 and from the filtrate copper was extracted with the extractants LIX 84I and LIX 622N in kerosene.

Secondary Copper Converter Dust Metal Recovery using

Flue dust was leached at room temperature with an alkaline solution of (NH4)2CO3 and NH4OH to solubilize ZnO and Zn metal. Some copper, lead, tin, and most of the zinc were dissolved in the leach step. Copper, lead, and tin were recovered in the cement product. The Zn in the filtrate was precipitated by pH adjustment to neutral using CO2 injection.

Recovery of zinc, copper, and lead-tin mixtures from brass

The Bureau of Mines has developed a process that fits these requirements. The technique consists of (1) dissolving zinc and copper from the dust with sulfuric acid, (2) recovery of copper by cementation, (3) recovery of zinc as zinc sulfate crystals, and (4) recovery of lead and tin as a salable residue.

Microbial recovery of metals from solids | FEMS

Microbial leaching processes are currently used for the winning of gold and copper from low-grade ores (‘bioleaching’). Solid industrial waste materials such as fly ash, sludges, or dust might also be microbially treated to recover metals for the re-use in metal-manufacturing industries.
